REQUEST FX LARGE SIZE ORDER FACILITY
The IdealPro Forex market center provides a Large-Size Order facility specifically intended for accounts which regularly submit orders in quantities greater than standard order maximums and are willing to trade outside the NBBO associated with the standard order minimum/maximum bands in an attempt to obtain faster fills. To be eligible for FX Large Order Size IdealPro you need to submit a written request to Client Service and that will initiate a review of the account's trading history and account equity. Please allow up to 7 days for the review to be completed.
